Reviews and Problems with TRENDnet TK-423K

Tripplite Cables Work With This

Summary: The only caveat is that the Tripplite cable does not include the speaker/microphone leads.But that's a separate cable with TRENDnet's anyway, and they're easy enough to find.

Pros: Works great. Good variety of KB shortcuts, too (read the whole instruction booklet.) I have a USB wireless KB and Mouse connected via position 4 to a server 15ft away. No loss or lag. Good price compared to competition. Includes mic and speakers.

Cons: A common complaint is that TRENDnet will not sell the longer cables separately. (You get two long and two short with this switch.) The short cables can really be too short. I ordered TrippLite's 6 ft. cable for the B042-Series KVM Switch (P780-006) from Newegg, item=N82E16812120587. Tried it and ...

Trendnet TK-423K 4 port

Summary: It's about time that KVM makers began to make reasonably priced KVMs that worked with DVI and Displayport connections and not 20+ year old VGA connectors. TImes have changed!

Pros: came with (way too short) cables. Also came with (way too short) audio stereo cables. Too short = 6'. Way too short = 4'. The unit seems well made with good action on the buttons.

Cons: Didn't work. No video, no KB and no Mouse switching. Weird cable setup: 1 USB + 1 PS2 with a warning on it NOT to use it if you use the USB connector. Video is done by old style 15 pin connector which is useless with a DVI or Displayport connector. A DVI (with the 4 analog) pins by the blade to a...

Excellent switch

Fantastic Product

Summary: Received it today and had it setup within 5 minutes. I was a bit confused at first because there was only a single USB lead on the client end of the cable, but that single USB connection allowed control of both mouse and keyboard on the 2 laptops I needed to control. Great product!

Great KVM Switch!!!

Summary: This is a great KVM switch. The hot keys work great and I have not had a single problem with losing the connections between my 3 computers, even during OS booting. I like that you can change the hot keys for keyboards that might not have a scroll lock key.

Summary: I really wanted to like this box, since it's nice and heavy and looks like it means business, but it just doesn't deliver all the goods. The two short cables everyone has mentioned are also fairly useless for a typical setup.

Pros: Very solid construction, snug cable fit, works most of the time.

Cons: I initially set this up with an older PS2 keyboard that I love and want to use until it dies. Everything seemed to work well, but then when playing a FPS game I found that it misses a lot of key presses. This means when you try to move your avatar, sometimes you'll just stand there and take a roc...

Works well, but not without a couple flaws

Summary: Compared to my previous PS2-only KVM by another "gear" company , this is a pretty nice unit. I haven't actually tried the sound, since I only use one of my computers for sound playback anyway. However, I may plug my USB headset into it to see if that works.

Pros: Sturdy build PS2 + USB support Double-scrolllock hotkey (as opposed to crazy combinations that my old one used) Separate button for each device on the unit rather than a single "next device" button. Device worked out of the box with my aging PS2 keyboard and two different USB mice attached to it ...

Cons: Two of the cables are annoyingly short - I was able to make it work, but most of my machines aren't all that close. After one month of use, one of the ports stopped working properly with USB (PS2 worked) - I tried a power cycle, swapping cables, swapping computers, but that wasn't enough. After 3...

Does the job and does it pretty well.

Summary: Got this for a PC workbench set up. Also got a TrendNet 5 port gigabit ethernet switch with Cat6 cables. The ethernet switch is plugged into a Netgear 500mbps Powerline adapter to connect to the modem-router & the ISP. All together makes a very functional small workbench set up.

Pros: So far does exactly what I need it to do, and does it quite well. Seems like a very good quality, well built unit. Like the two sets of "shorter" and two sets of "longer" monitor/KB/M cables. Like the option of USB or PS2 connection for the KB/M for the master as well as PC connections. Monitor c...

Cons: As is, would be a superb value at $99.99. For $129.99, would be a superb value if also came with 4+1 VGA-to-DVI adapters to accomodate DVI monitor & PC video hookups, as well as a USB on the back (to connect a master file HDD) and a USB on the front (to connect a flash drive). Also, a black case ...
